Road Crush Edmonton | 20mm Crushed Gravel for Driveways & Bases

Before you pour concrete, lay paving stones, or spread driveway gravel, you need a sub-base that won’t sink when things get heavy. Around Edmonton, that typically means starting with 20mm road crush.

This is a raw, heavy-duty mix of crushed fractured rock and fine stone dust. It’s designed specifically for compaction. When you run a plate tamper over it, the sharp, jagged edges lock tightly together while the stone dust fills every remaining pocket. Once it’s packed down, it forms a dense foundation that handles vehicle traffic and resists shifting through Edmonton’s spring thaw cycles.

Contractors already know the drill with this material — but if you’re tackling a weekend patio or driveway project yourself, just remember: this is your heavy bottom layer. Dump it, level it, pack it tight, and then worry about your bedding layers or concrete on top.
Drive into our West Edmonton yard and we’ll load your truck or commercial trailer directly. For deliveries anywhere across Edmonton, St. Albert, Sherwood Park, and Spruce Grove, we can drop a loose bulk load by dump truck, deliver it in a Big Bag, or provide 5 Gallon Bags if you just need to fill a few deep ruts.

What It’s Used For:
Driveway Foundations: The heavy bottom layer for gravel, asphalt, or concrete parking pads — compacted before anything else goes down.
Hardscape Sub-Base: Sits directly beneath patio stones and walkways to keep the ground from settling unevenly.
Retaining Wall Bases: Packed into the trench beneath wall blocks so they sit level and stay level.
Shed & Garage Pads: The standard sub-grade material before pouring concrete floors or setting skids.

Once your road crush is down and fully compacted, you’re ready for your next layer. For patio and walkway projects, take a look at our Paver Sand for the final levelling layer before your stones go down. If you’re looking for a versatile crushed limestone that works as both a compactable base and a decorative finish, check out our Limestone Crush.
